Related Test Equipment - ASTM B117 Chamber
ASTM B117 Chamber is used to evaluate the corrosion resistance of materials and coatings.
Structural composition
chamber: one molding upgraded FRP material, Strong corrosion resistance, reinforced design, long service life and high temperature resistance.
Spray system: including nozzle, salt liquid storage tank, spray pump and other components.
Heating and constant temperature system: equipped with heating elements and temperature sensors, the temperature in the test chamber can be controlled within the specified range.
Sample holder: round rod and V-shaped groove design, sample placement Angle can be adjusted.
Control system: can set and control the test temperature, spray time, spray cycle and other parameters, but also with fault alarm and safety protection functions.
Working principle
A 5% concentration of sodium chloride solution is atomized to form a salt spray, and the material or coating sample to be tested is placed in a corrosive environment with high humidity and high salinity. The corrosion resistance of the material or coating is evaluated by observing and measuring the appearance, weight, performance, etc., of the sample before and after the test.
